Product details
Overview
TZA3011BVH/C2,551 from NXP Semiconductors (formerly Philips Semiconductors) is a high-speed laser driver IC for DC-coupled laser diodes in optical transmission systems up to 3.2 Gbit/s. It delivers bias and modulation currents up to 100 mA each, supports dual-loop optical power and extinction ratio control (150 µA–1300 µA average monitor current; ER = 5–15), and operates with 3.3 V or 5 V laser supply voltage. It is used in SDH/SONET line cards requiring stable, temperature-independent laser output.
For engineers reviewing the TZA3011BVH/C2,551 datasheet, TZA3011BVH/C2,551 pinout, TZA3011BVH/C2,551 application, or TZA3011BVH/C2,551 equivalent, key selection criteria include DC-coupling support, dual-loop control bandwidth up to 2.7 Gbit/s, 80 ps rise/fall times, PECL/LVPECL/CML compatibility, and HBCC32 thermal-enhanced package suitability for high-density RF layouts.
Technical Context
The TZA3011BVH/C2,551 implements a dual-loop control architecture that independently regulates optical average power (via AVR pin) and extinction ratio (via ER pin) using real-time photodiode current feedback from the MON pin. Its RF output stage uses a bipolar differential pair optimized for DC-coupled lasers, delivering 2 V dynamic range at LA pins with 1.2 V minimum output voltage under 5 V VCCO.
It accepts differential PECL/LVPECL/CML data and clock inputs (100–1000 mV p-p), features retiming synchronized to the rising clock edge, and includes pulse width adjustment (±100 ps) via external resistor on PWA. Alarm functions monitor operating current (ALOP) and monitor diode current (ALMON) with programmable thresholds via MAXOP/MAXMON pins.
Key Specifications

Pinout & Package
Package: HBCC32 (plastic thermal enhanced bottom chip carrier; 32 terminals; body 5 × 5 × 0.65 mm; SOT560-1). Thermal resistance junction-to-ambient is 35 K/W on 4-layer PCB with 9 plated vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCCA, VCCD, VCCO | Analog, digital, and RF output supply rails | Separate supplies isolate noise-sensitive analog control loops from digital logic and high-current RF outputs |
| LA / LAQ | Differential laser modulation outputs | LA drives laser anode; LAQ sinks complementary current into dummy load - enables true differential RF drive with 100 Ω Zo |
| BIAS | Laser bias current source output | Low-voltage compliance (0.8 V min @ 5 V VCCO) supports direct connection to laser cathode in DC-coupled topology |
| MON | Monitor photodiode current input | RF-input node with 27 Ω impedance - accepts fast photodiode signals without AC coupling, critical for dual-loop stability |
| AVR / ER | Control loop setting inputs | Current-sink inputs (−15 µA to −280 µA AVR; −5 µA to −35 µA ER) set average power and extinction ratio via external resistors |
| ALOP / ALMON | Open-drain alarm outputs | Assert low on overcurrent conditions - interface directly to FPGA GPIO or supervisor ICs without pull-up redesign |
| ACDC | Coupling mode select | Grounded for DC-coupled operation (TZA3011B); left open for AC-coupled (TZA3011A) - configures internal output stage biasing |
Key Features
| Feature | Design Value |
|---|---|
| Dual-loop optical control | Maintains constant 'one' and 'zero' optical levels independent of laser temperature and aging - eliminates manual recalibration in field-deployed modules |
| DC-coupled laser support | Optimized output stage with 0.8 V BIAS min voltage and 5 V VCCO capability - enables direct-drive of uncooled DFB lasers without external bias-T circuits |
| Retiming function | Synchronizes data to clock on rising edge, reducing deterministic jitter - improves BER in long-haul links with degraded clock recovery |
| Pulse width adjustment | ±100 ps fine-tuning via external resistor on PWA - corrects duty cycle distortion from asymmetric laser turn-on/turn-off dynamics |
| Integrated alarm monitoring | Two independent open-drain alarms (ALOP, ALMON) with programmable thresholds - provides early warning of laser degradation or catastrophic failure |
| PECL/LVPECL/CML compatibility | 100–1000 mV p-p input swing with internal common-mode generation - simplifies interface to TI, Broadcom, or Marvell SerDes without level-shifting components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar laser driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX3736AETE+ | Single-supply 3.3 V operation; no 5 V VCCO support; max 2.5 Gbit/s; no integrated retiming | Suitable only for lower-speed, AC-coupled VCSEL drivers; lacks dual-loop ER control | Select when cost sensitivity outweighs speed and optical stability requirements; verify photodiode feedback loop design separately |
| ADN2880ACPZ-R7 | Supports 3.2 Gbit/s but requires external bias controller; no integrated dual-loop AVR/ER; higher jitter (25 ps p-p) | Used in legacy SONET designs where discrete bias control is already implemented | Choose only if existing board layout cannot accommodate HBCC32 footprint or if dual-loop integration adds unnecessary complexity |
Compared with MAX3736AETE+ and ADN2880ACPZ-R7, the TZA3011BVH/C2,551 uniquely integrates DC-coupled 5 V laser drive, dual-loop optical stabilization, and retiming in a single HBCC32 package - reducing system-level component count and enabling plug-and-play optical power calibration without firmware intervention.

FAQ
What is the maximum data rate supported by the TZA3011BVH/C2,551?
The TZA3011BVH/C2,551 supports data rates from 30 Mbit/s up to 3.2 Gbit/s, covering OC-48/STM-16 and Fibre Channel 2G/4G standards. Its 80 ps rise/fall time and <20 ps peak-to-peak jitter ensure signal integrity at full speed, validated per SONET GR-253-CORE jitter tolerance requirements.
How does the TZA3011BVH/C2,551 implement dual-loop control?
The TZA3011BVH/C2,551 uses two independent feedback loops: one sets average optical power via the AVR pin (150–1300 µA monitor current range), and the other controls extinction ratio via the ER pin (5–15 linear scale). Both loops sample the MON pin's photodiode current and adjust BIASOUT and MODOUT to maintain stable 'one' and 'zero' optical levels across temperature and laser aging.
Can the TZA3011BVH/C2,551 drive a 5 V laser diode directly?
Yes. The TZA3011BVH/C2,551 supports VCCO up to +5.3 V and delivers 0.8 V minimum bias voltage at the BIAS pin under 5 V operation - enabling direct DC-coupled drive of 5 V laser diodes without external level-shifting or bias-T networks, as confirmed in Table 5 limiting values and Section 7.4.
What is the purpose of the ACDC pin on the TZA3011BVH/C2,551?
The ACDC pin configures the output stage for coupling mode: leave unconnected for AC-coupled lasers (TZA3011A), or ground it for DC-coupled operation (TZA3011B). For TZA3011BVH/C2,551 - a TZA3011B variant - grounding ACDC enables internal biasing optimized for direct laser anode/cathode connection with 5 V VCCO support.
Does the TZA3011BVH/C2,551 include built-in protection features?
Yes. The TZA3011BVH/C2,551 integrates alarm functions on operating current (ALOP) and monitor diode current (ALMON), soft-start for bias/modulation currents at power-up, and enable-controlled laser shutdown. Thresholds are set via MAXOP/MAXMON pins, and alarms assert open-drain low - allowing direct interfacing with host microcontrollers for predictive maintenance.
